ARINC 653 introduces the concept of partition that allows time and space isolation in real-time avionic systems. Tasks are assigned to partitions according to various objective functions or constraints such as safety, performance, and security. Some

International audience; The paper describes a new RNS modular inversion algorithm based on the extended Euclidean algorithm and the plus-minus trick. In our algorithm, comparisons over large RNS values are replaced by cheap computations modulo 4. Com
